and find JDE 4.1.0. Downloads and installs fast. You may
need to install the latest java, but I'm not sure -- the JDE will tell you if you need that particular upgrade.
After installation of the JDE, it works like this: First, backup your content store on your real BB to somewhere on your harddrive where you know what it is. Then unplug the cable.
Second, from your Start menu, start "MDS". A DOS screen will open and it looks like a large BAT file runs. Note: You have to have your internet connection open.
Third, from your Start menu, start "Device Simulator". Another DOS screen opens, and then in a couple of seconds a simulated BB appears. I think, at this point, you can change the simulation to your BB, but I've never had to do it so I'm not sure how -- but it should be eezy. However, I'm 99 percent sure you don't have to have matching units for this to work, since in real life you can back up from one BB and restore to another model.
Fourth, simulate a USB connection. From the top menu on the simulator, choose "Simulate" and then "USB Cable Connection".
Fifth, start your Desktop Manager. It will respond as though the simulation is an actual BB! Then use the Desktop Manager to restore the content store that you backed up in step "First" to the simulation.
Sixth, using the simulation, surf around the internet to pictures/ringtones/etc you may like, and download them to the simulation.
Seventh, use the Desktop Manager to back up the content store from the Simulation. Then shut down all the programs, including MDS, the Simulation, and the desktop manager.
Eighth, connect your real BB via USB to the computer, start Desktop Manager, and restore the content store you backed up from the simulation in step "Seventh".
Voila! Pix and other stuff transferred to your pre-4.2 device!
Note: When you do a restore operation, it always erases current data before restoring. That's why it's essential
to back up the real BB into the simulation, then the simulation back into the real BB, so you don't lose the stuff you already have on your real handheld.
All this sounds complicated, but after you do it a couple of times, it's really only a few mouse clicks!
